PROCESS OF MANUFACTURING ARTIFICIAL AIGFIETS.

SPECIFICATION forming part of Letters Patent No. 785,321, dated March21, 1905.

Application filed September 23, 1904:. Serial No. 225,607.

To all whom, it may concern:

Be it known that I, ROBERT L. MCLAUGH- LIN, a citizen of the UnitedStates, residing in Lakeview, in the county of Passaic and State 5 ofNew Jersey, have invented certain new and useful Improvements inProcesses of Manufacturing Artificial Aigrets; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will I enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

I My present invention has for its object the manufacture of artificialaigrets or other similar articles. The article which is the product ofmy process forms the subject of an application for Letters Patent of theUnited States filed of even date herewith.

In carrying out my process of manufacturing an imitation of the ordinaryaigret certain filaments which are to form the barbs thereof are firstsecured to and along the stem 5 or shaft thereof at suitable intervalsin such manner that the point of attaching each to the stem comes at themiddle of the filament, thus leaving about the same length or onehalf ofthe filament on both sides of the shaft.

3 Then by suitable means the halves of the filaments are caused to bepermanently bent so that each half is convergent, relatively to the stemand also to its complement, all those. on each side of the stern beingapproximately 3 5 parallel, all in imitation of the genuine aigret.

Broadly, my process of manufacturing an imitation of the ordinary aigretconsists in the foregoing. I have in practice, however, found itadvantageous, principally in point of 4 economy of material, labor, andtime, to introduce certain features not specifically mentioned in theforegoing. These I will set forth in reference to the conduct of myprocess as now practiced by me and now to be described and then pointthem out in the claims.

In the accompanying drawings, Figure 1 shows a drum having gummedstifiened attenuated pieces which are to form the aigret shafts or stemsheld thereon at angular portions thereof by a winding of sized silkpass- 5 ing around about one half of each of said pieces and leaving theother half temporarily free and also how a certain cutting of the silkis efiected. Fig. 2 shows one of the aigrets after removal from the drumand after the free part of its stem has been laid on and made to adhereto that to which the silk filaments formed as in Fig. 1 have becomeattached by the gum thereof. Fig. 3 shows how the filaments aredeflected by a suitable fiuid- 6O jet. Fig. 4 is a magnified fragmentaryview of the aigret as shown in Fig. 2, a portion of the top layer of theshaft being broken away to show the gum. Fig. 5 is a magnified view inperspective of a fragment of one of 6 5 the sized filaments, and Fig. 6illustrates one way of securing the proper binding together of the partsof the aigret.

I first cut thin celluloid into long narrow strips a. These are thenapplied to the drum 7 b so that one-half of each lies along one of theopposite angular portions 0 of said drum, which is of polygonal shape,and there held bya suitable fastening means, such as clips 0Z. Said drumis journaled in a frame 6 and may be rotated by a crank f. Before beingplaced on the drum the strips are gummed on one side from end to end, asat g in Fig. 4, and these gummed sides are out when the strips aresecured to the drum. I then take a silk, cotton, or other suitablethread h, coated with a preferably waterproof material 2 and wind it onthe drum in spiral uniformly-spaced coils from end to end of the drum.On account of the strip a being laid on the angular portions 0 5 of thedrum the thread has a good adhering contact with the portion of thestrip a over which it is wound. A knife j is then drawn across thespirals of thread, longitudinally of the drum and on both sides thereof,midway between 9 the two strips. The strips, with the severed threads orfilaments attached, can now be removed from the drum, whereupon the freeportion is of each strip is laid on that to which the filaments areadhering and made itself to adhere thereto from end to end. This step ofsecuring together the two portions of the strip may, if desired, comeearlier in the operation, as immediately before or after the cutting ofthe thread. The aigret is now complete, with the exception of shapingthe filaments. Zin Fig. 3 designates a fluid-jet. The aigret is nextpresented endwise to this jet and there held until the filaments havebeen bent thereby at or adjacent the stem in such manner that the twohalves of each stand convergent to each other and to the stem, as bestillustrated in Fig. 3.

In practice I prefer that the jet used be a steam-jet, for then thepermanency of the bending back of the filaments will be insured by thesizing being first caused by the machine to slightly soften, and then,after removal from the jet, to harden or set, and thus retain thefilaments in the defiectedposition.

If the two portions of each strip are made to adhere to each otherbefore their removal from the drum, this can be done conveniently and insuch a manner as to keep the parts accurately disposed until theadhesive sets by first laying the free portion of each strip on itscomplement after the winding of the thread is finished and then windinga binding-strip of tape on around the whole, as in Fig. 6. When theadhesive thoroughly sets, the tape can be removed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. The process of manufacturing artificial aigrets which consists inattaching a series of filaments, each in its middle portion, to anattenuated strip at approximately uniform intervals along the latter,and then substantially simultaneously bending the free or projectingportions of said filaments into permanent convergence those on one sideof said strip with those on the other, substantially as described.

2. The process of manufacturing artificial aigrets which consistsin-attaching a series of filaments, each in its middle portion, to anattenuated strip at approximately uniform intervals along the latter,and then presenting said strip, with said filaments attached, endwise tothe action of a fluid-jet, whereby to substantially simultaneously bendthe free or projecting portions of said filaments into permanentconvergence those on one side of said strip with those on the other,substantially as described.

3. The process of manufacturing artificial aigrets which consists inlaying an attenu ated strip longitudinally on a suitable mandrel,winding a thread around the mandrel and the strip in substantiallyuniform coils filaments formed by cutting the coils into permanentconvergence those on one side of said strip with those on the other,substantially as described.
